The invention discloses a full-hydraulic self-propelled
paddy field spray tumbrel which is back-guided, three-front-wheeled, self-propelled and full-hydraulic
paddy field spray fertilization equipment, adopts an M-type frame design and an adjustable cross beam, and is driven by a large-torque
hydraulic motor. The
paddy field spray tumbrel adopts a multifunctional design and has a fertilization mode, a leaf surface spraying mode and a line-by-line rice
seedling weeding spraying mode, wherein in the fertilization mode, the
fertilizer applicator is mounted at the front part of a frame, and a high-speed
hydraulic motor is used for driving a throwing wheel with an adjustable pitching angle to perform uniform fertilization operation; in the leaf surface spraying mode, a swing
sprayer with adjustable height and angle is mounted at the rear part of a tumbrel seat and can be used for large-area leaf surface spraying operation; in the line-by-line rice
seedling weeding spraying mode, the spraying height of a line-by-line rice
seedling sprayer can be controlled according to weeds under paddy rice, and a spraying head can be used for spraying under paddy rice leaves in the middle of the paddy field, thereby avoiding the coverage of the paddy rice leaves to chemical liquid. According to the paddy field spray tumbrel, the large-area efficient fertilization spraying operation of the paddy field can be performed, the problem of no
mechanical assistance during the middle and later-period management of the paddy field is solved, the labor intensity is greatly reduced, and the efficiency is improved.
